Microsoft’s Windows 11 July 2026 Security Update arrives on
Tuesday, 14 July 2026
, and this month’s release includes several significant changes that will directly affect how UK SMEs manage system recovery, network authentication, and printer configuration. Unlike routine patches that simply close vulnerabilities, this update introduces new default behaviours that your IT systems will adopt automatically—and some require storage space and planning you need to know about now.
If your Kent or South East business runs Windows 11 versions 24H2 or 25H2, here’s what’s changing in four days and what you should prepare for today.
1. Point-in-Time Restore: New Recovery Feature Requires 200GB Free Storage
The headline feature in this update is
Point-in-time Restore, a new recovery feature designed to quickly roll back a system to a previous good working state
. This could prove invaluable when a failed update, problematic software installation, or system corruption leaves a workstation unusable.
The feature works automatically and creates restore points that include settings, files, and apps using the Volume Shadow Copy Service (VSS)
, the same technology Windows has used for years in System Restore and backup applications.
The catch:
Point-in-time Restore comes enabled by default in the Home and Pro editions of the operating system. However, the system must have at least 200GB of storage
. If your workstations have smaller SSDs or limited free space, the feature won’t activate, but you should check now to avoid confusion when staff expect the feature and find it unavailable.
What UK SMEs should do:
- Audit your Windows 11 devices to identify which have 200GB+ free storage
- Check Settings > System > Recovery after 14 July to confirm the feature is active
- Consider whether you want this enabled on all devices or prefer centralised backup strategies
- Review
Settings > System > Recovery where you can turn the recovery feature on or off, configure the restore point frequency and retention, and decide how much storage the feature uses
For organisations with established business continuity and backup procedures, Point-in-Time Restore offers an additional layer of protection, particularly for mobile workers or remote staff whose devices may not be included in regular backup schedules.
2. Kerberos RC4 Hardening: Final Enforcement Phase Begins 14 July
If your business runs a Windows domain—common in offices with multiple computers sharing resources—you need to know that
the final deployment phase for Kerberos RC4 hardening begins with the July 2026 Windows security update
.
Kerberos RC4 hardening is Microsoft’s multi-phase effort to deprecate RC4 encryption in Kerberos authentication protocols across Windows domains. RC4 (Rivest Cipher 4), while still NIST-approved for legacy use, has known weaknesses that make it vulnerable to modern attack techniques
.
After 14 July,
RC4 encryption in Kerberos authentication is disabled by default
, which improves security but may cause authentication failures with older systems, applications, or network devices that haven’t been updated to use modern encryption.
What UK SMEs should do:
- Test authentication for all business-critical applications after the update
- Check whether any legacy systems, network printers, or specialist software still require RC4
- Review Event Viewer logs for Event ID 4649, which identifies systems attempting to use RC4
- Contact software vendors if authentication issues arise with older applications
Most modern Windows environments will transition smoothly, but businesses running older servers or specialist equipment should monitor authentication carefully in the week following 14 July. This change affects server infrastructure and domain-joined devices, not standalone workstations.
3. Windows Ready Print: New Default for Printer Installation
Printing configuration changes in this update.
Starting in July 2026, new printer installations will default to Windows Ready Print where supported, enabling a simpler and more reliable setup experience
.
Starting with the quality update for July 2026, the operating system will install printers by default using the Internet Printing Protocol (IPP), provided the device is supported
. This modern standard eliminates the need for manufacturer-specific drivers in many cases, reducing compatibility issues and simplifying printer management.
Most network printers manufactured in the past five years support IPP, but older devices may require manual driver installation if they don’t.
What UK SMEs should do:
- Test printer installation and functionality after the update, particularly with older network printers
- Keep manufacturer drivers available for legacy devices that don’t support IPP
- If you encounter issues,
open Settings > Bluetooth & devices > Printers & scanners, and turn off the “Default install printer using Windows Ready Print” option
to revert to traditional driver-based installation
4. Pause Windows Updates Indefinitely: More Control for IT Managers
For the first time,
this release introduces new Windows Update changes that allow users to pause updates indefinitely
. Previously, Windows 11 limited pauses to a few weeks before forcing installation.
This gives UK businesses greater flexibility to schedule updates around busy periods, but it also increases the risk that staff will defer critical security patches indefinitely. The change is
a practical compromise between security and user control
, but it requires clear IT policies to prevent systems from falling months behind on patches.
What UK SMEs should do:
- Set a company policy for maximum update deferral periods (we recommend no more than 30 days for security updates)
- Use Group Policy or Microsoft Intune to centrally manage update schedules if available
- Monitor which devices are paused and for how long to avoid security gaps
- Educate staff that pausing updates should be temporary, not permanent
This flexibility is useful for businesses that need to defer updates during critical work periods, but managing Microsoft’s increased patch volumes requires discipline to ensure security updates are applied promptly.
5. File Explorer Performance Improvements and UI Refinements
On a more practical note,
after installing this quality update, you’ll notice that File Explorer will launch faster thanks to new speed improvements
. Microsoft has also refined several interface elements, including
changes to the Widgets feature to make the experience quieter and less distracting
.
These aren’t headline features, but
faster File Explorer performance, Bluetooth reliability improvements, and less intrusive Widgets aren’t headline-grabbing changes. However, they’re often the updates that have the biggest impact on how the system feels after months of daily use
.
What Volume Should UK SMEs Expect from This Patch Tuesday?
Microsoft’s June 2026 Patch Tuesday set a new record with 200 vulnerabilities addressed.
Microsoft’s July 2026 Patch Tuesday arrives one month after the record-breaking June release of 200 vulnerabilities. This month is expected to show normalization from June’s extraordinary volume while maintaining the elevated baseline that has characterized 2026
.
Security analysts
estimate 100-140 vulnerabilities
for July, which remains significantly higher than historical averages but lower than June’s unprecedented volume. UK businesses should still allocate testing time and prepare for a substantial update package.
Testing and Deployment: A Practical Timeline for Kent Businesses
The update begins rolling out on 14 July, but Microsoft uses a phased approach, so not all devices receive it immediately. Here’s a sensible deployment strategy:
- 14–15 July: Allow the update to install on a small test group of non-critical workstations
- 16–17 July: Monitor for issues with authentication, printing, storage warnings, and application compatibility
- 18–21 July: Roll out to remaining workstations if no major issues identified
- 22 July onwards: Address any device-specific problems and ensure all systems are current
This staged approach ensures you catch problems early without disrupting your entire office if something unexpected occurs.
Need Help Managing Windows 11 Updates Across Your Business?
